The metal pipe body has the characteristics of light weight and rapid temperature equalization, so that the metal pipe body has excellent thermal superconducting performance. When the heat pipe works, the surface of the cavity body presents the characteristic of rapid temperature equalization through the back-and-forth convection of gas and liquid in the metal pipe body between the heat absorption end and the heat release end, thereby achieving the purpose of heat transfer.

The product 100 is provided with a heat pipe 120, and the heat pipe 120 is mounted on the outer shell of the product 100 through a fixing mechanism 130. When the user uses the product 100, the temperature of the electronic component rises to cause the heat pipe 120 to start dissipating heat, and at the same time, the liquid at the heat absorbing end in the heat pipe 120 body slowly vaporizes due to being heated and flows to the heat releasing end, and the gas condenses into liquid at the heat releasing end and then flows back to the heat absorbing end through gravity, capillary force, centrifugal force and the like. When the production specification of the heat pipe 120 is not qualified, and the user is inverting the product 100 quickly, the liquid at the heat release end of the heat pipe 120 may directly drop to the heat absorption end, so as to generate the water drop sound, which may generate a bad experience for the user using the electronic product, and affect the use enthusiasm of the user on the electronic product.
In view of the above, it is necessary to develop a heat pipe detecting device to measure the inclination angle and the heating temperature of the heat pipe, and determine whether the inclination angle and the heating temperature meet the production standard, so as to reduce the probability of defective products entering the market.
